Converting NSData to Integer in Swift

Question

In Objective-C the code looked liked this and worked flawlessly,

NSInteger random = arc4random_uniform(99) + 1 
NSData *data = [NSData dataWithBytes:& ra         


        

Answer 1

My contribution with a swift 3.1 extension :

extension NSData{
    var int :  Int{
        var out: Int = 0
        self.getBytes(&out, length: MemoryLayout.size)
        return out
    }
}

Just call .int to get your value, just like this :

let value = 50
let data = NSData(bytes: &value, length: 4)
print(data.int)
